Rapping produces sounds of an indefinite pitch, I notated as chanting on the tonic note or as little steps up from tonic. The composition lacks intervallic saturation thus its artistic meaning of piano cover and expression suffer.
Imitate the vocal delivery by Machine Gun Kelly or it won't sound as the song. The vocal part is relatively rigid and precisely timed, but it produces not much of a melody for the right hand. A predominant vocal style is *staccato*.
"don't let me go" is played with a straight rhythm in quadruple time 12/8. It is easy to count for beginners; accent all 4 strong beats to maintain a steady pulse. Practice slowly along with the recording.
To keep listeners attention, the *chorus* of "don't let me go" was made to be the loudest part of the song. I colored it *blue* for your convenience: it is easier to learn a piece of music when you have a mental scheme of it. Play every part differently, as expressively as possible. If some notes are too difficult to play, omit them focusing on emotions instead of sightreading.
A single vocal line accompanied by an instrumental riff constitutes the entire musical texture. "don't let me go" has a semi-improvised, loosely organized and wandering melody and homophonic arrengement: the instrumental part provides a harmony to support the vocal but lacks its own worthy melody.
"don't let me go" is transcribed in the original key, E Flat Major, but the piece is atonal: it has no tonic/sub/dominant relations.
Instead of a progression it and uses three bass tones E♭ E♭/A♭ E♭/B♭ with a riff.
